CONE CRUSHER Russian patent published in 2010 - IPC B02C2/04 

FIELD: process engineering.

SUBSTANCE: invention relates to crushing equipment and can be used at mineral processing equipment. Proposed crusher comprises stationary and moving work cones. Note here that stationary cone work surface has ring-like ledges directed towards inlet hole, while moving cone surface has ledges located at its lower part and long generating line of moving cone with length equal to 0.25-0.5 of generating line length and height decreasing towards cone smaller diametre. Moving cone unloading side has ring-like ledge preventing falling out of larger particles, ledge height being determined by the formula: h=a₁-a₂, where h is ring-like ledge height; a₁ is distance between stationary and moving cones at given point; a₂ is the same on the side whereon work surfaces approach to maximum extent.

EFFECT: power savings ensured by increased load on crusher work volume.
